program(_:unbindValueForSymbol:atLocation:programID:renderer:)

Invoked on the delegate to let it unbind program values and/or also unbind associated graphic resources (such as textures).

Declaration

optional func program(_ program: SCNProgram, unbindValueForSymbol symbol: String, atLocation location: UInt32, programID: UInt32, renderer: SCNRenderer)

Parameters

  • program:

    The SCNProgram object to unbind values for.

  • symbol:

    The name of the symbol to unbind a value for.

  • location:

    The location of the symbol within the program object to be modified.

  • programID:

    The underlying OpenGL program object in which the unbinding is done.

  • renderer:

    The renderer that is currently rendering the scene.

Discussion

If you use the handleUnbinding(ofSymbol:handler:) method to associate a handler block with a SceneKit object for a symbol, SceneKit will not call the delegate’s program(_:unbindValueForSymbol:atLocation:programID:renderer:) method for that symbol when rendering that object.
